Improve rules features

[l2eused]

1. add prompt popup alert when press "reload" button (reset to default rules), for accident pressing

2. find and alerts duplicate rules (or interupt rule), suppose that no one want this happen and might helper to find out for someone who have long rules

   example: when having 'dpx|' -> 'abcd|' and 'dpx|' -> 'dpxls|'

3. add sequence rule

   example: 'w/ |' -> 'with |' -x 'w/ |' instead of seperate 2 rule, 'w/ |' -> 'with |' and 'with |' -x 'w/ |'

   use case: in currently, if I have sentence like this comment with the word and want to deleting, when with | it will also trigger rule and convert to w/ . As the rule 'with |' -x 'w/ |' is mainly purpose to undo 'w/ |' -> 'with |' rule, it should avoid to trigger rule when w/ | didn't active before.

   In case of --> and →, when I want to delete →, I need to press 4 backspaces instead of just 1 backspace.

   This feature should be, 'w/ |' -> 'with |' -x 'w/ |', type w/ , trigger with and listen, if pressing backspace, trigger w/ else execute -x 'w/ |' rule. When have with and press backspace, nothing happen cause -x 'w/ |' need 'w/ |' -> 'with |' to trigger before.

Thank you for the suggestions! The concept of chained rules has been on my mind for a long time, and I plan to do a code refactor before proceeding with this task.
